The 27 Best Anti-Aging Tips of All Time

Add this to the already-long list of reasons to quit. While less serious than reducing your chances of getting lung cancer or heart disease, smoking also damages your looks. The habit takes a major toll on your appearance, contributing to premature skin aging, wrinkles, stained teeth, and even increased psoriasis risk.

“Smoking increases wrinkles due to facial motion, and it also has a vasoconstricting effect, which means it chokes off blood vessel circulation,” says dermatologist David Stoll, MD, author of A Woman’s Skin. 

You probably already know that foods like kimchi, sauerkraut, tempeh, and other probiotic-rich foods are good for your gut. Turns out they may also combat premature aging.

“Fermented foods have excellent antioxidant and anti-inflammatory properties,” says Craig Kraffert, MD, a board certified dermatologist and president of Amarte.

Beauty products that are made with fermented extracts may also make a difference. Dr. Kraffert recommends products that contain ingredients like fermented gingko biloba nut or mushroom extract. “The most commonly cited benefits of fermented extracts within skincare products are skin calming and brightening,” he says. 

As if the risk for obesity, diabetes, and heart disease wasn’t enough, sugar may take a toll on your skin, too. In a 2010 study, researchers found a link between dietary sugars like glucose and greater production of advanced glycation end products (AGES).

But if you have a sweet tooth, don’t panic just yet. “The supportive scientific and clinical data, while growing, remains limited,” says Dr. Kraffert. So enjoy sugar in small amounts, and focus more on  leading an active lifestyle and eating an overall balanced diet.

Always sleep on your side? The habit could be causing lines to form on the cheek that’s constantly pressed against the pillow. “Sleeping on one side can definitely cause wrinkles on that side alone,” says Dr. Stoll. “I’ve seen this many times.”

Side-sleepers may want to switch to their backs—and not just to prevent wrinkles. Back-sleeping eases neck and back pain, fights acid reflux, and even helps prevent saggy breasts.

Not a natural back sleeper? Try the Night Pillow ($150; amazon.com); the material won't irritate your skin if you switch to your side or stomach during the night.

Exfoliating using beads or chemical peels is a go-to skincare strategy for sloughing off dead skin and revealing a smoother complexion underneath—but it’s important to make sure you’re not aggravating your face in the process. “Too much exfoliation is counterproductive,” says Dr. Stoll. He recommends talking to your dermatologist about the best exfoliation method for your skin type.

If you only have one anti-aging product in your medicine cabinet, make it a retinoid. Dermatologists love this powerful skincare ingredient (a derivative of vitamin A) for its ability to accelerate cell renewal.

“Retinoids turn over skin cells and boost collagen production, which leads to more youthful-looking skin,” says Dr. Lamb.

New to retinoids? The ingredient can be drying, so start off slowly by working products with a lower percentage into your regimen, and then working your way up. For an over-the-counter option, we love Roc Retinol Correxion Deep Wrinkle Night Cream ($14; amazon.com), which is one of the highest strength, non-prescription formulas you can get. 

You already know that eating high-sodium foods make your body retain water, leaving you feeling heavy and bloated. So it should come as no surprise that super-salty fare triggers a similar response in your face, giving you a puffier appearance (under your eyes, for example). To cut back gradually, start cooking with salt-free flavor boosters such as chili peppers, lemon juice, and fresh herbs. Not only will you look less bloated, but a low-sodium diet will also reduce your risk of high blood pressure and stroke.

Speaking of drinking: Alcohol dehydrates the body, so think twice before having that second glass of wine. “Dehydrated skin is more likely to appear dry, sallow, dull, and crepey,” Dr. Nussbaum says. Be especially careful of white wine: the acid in white wine can damage your enamel and make your teeth more susceptible to long-lasting stains.

Another often-forgotten patch of skin: your chest. Too much sun exposure when you're young may leave you with blotchy, freckled skin in the short term, and down the line, you may notice wrinkles, loose skin, and white spots.

“Your best bet is to stop daily damage before it gets serious,” says Dr. Kraffert. To keep your décolletage from deteriorating, wear sunscreen on days you're not wearing clothing that covers your chest.  

And if you already have sun damage, moisturize the area before bed with an over-the-counter retinol such as Neutrogena Rapid Wrinkle Repair Moisturizer SPF 30, or with a cream that contains melanin production inhibitors to brighten skin. “Adding other skin-brightening ingredients such as sulfur and botanical extracts will help, too,” says Dr. Kraffert. 

You know you’re supposed to do it, but sometimes you just… don’t. We get it. But experts stress that failing to wash your face at the end of the day is a major missed opportunity for skin to regenerate while you sleep (not to mention, it ups your chances of waking up with clogged pores).

“Skin renews itself overnight, so if you want to change the way your skin functions, the most important ingredients should be applied before bed,” Olga Lorencin-Northrup, founder and lead aesthetician of Kinara Spa in Los Angeles previously told Health.

You should think of sleep as being another essential step in your skincare routine. “Sleep is super important in allowing the body to regenerate, and the skin is no different,” says Dr. Nussbaum. Not only will plenty of shut-eye let skin cells regenerate overnight, but it will also help prevent dark under-eye circles, she says. Certain foods can also help you sleep so stock your fridge with these sleep inducers if you're having shut eye issues.

Booking regular appointments with your dermatologist will ensure that you’re up-to-date on the latest anti-aging skincare developments. Your doctor may recommend treatments for more dramatic results than you’d get from home remedies or even from a trip to the spa.

For example, Dr. Stoll says he might suggest an exfoliating peel that contains glycolic or trichloracetic acid for patients. “Aestheticians can legally use up to 20%, but doctors can use stronger strengths, like 70% glycolic acid,” he explains.  

Moisturizing takes more effort than just slapping some lotion on your face. All those pricey anti-aging products you’ve invested in will work more effectively if you use them on clean, moist skin, says Dr. Kraffert. When you get out of the shower, he suggests applying lotion within three minutes—before water on skin has a chance to fully evaporate. “Not only will you get the benefits of the moisturizer itself, but you’ll help seal in the hydration from the water,” he explains. “If you wait too long and that water evaporates from your skin, it can take some of your body’s natural moisture with it.”

Experts are divided on whether or not a diet that includes lots of vitamin C superfoods such as citrus, peppers, and kale can ward off signs of aging. But it certainly can't hurt to add more of these foods to your plate. In a 2007 study published in the American Journal of Clinical Nutrition, researchers found that people who ate vitamin C-rich foods had fewer wrinkles and less age-related dry skin than those who did not.

A vitamin C serum may offer more noticeable benefits. “Topical vitamin C is much more important for preventing wrinkles than oral vitamin C,” says Dr. Stoll. Our top pick: Mad Hippie Vitamin C Serum ($27; amazon.com) which packs anti-aging benefits without breaking the bank.

Stained, yellowed teeth can add years to your face. To feel more confident about your smile, remove stains with whitening toothpaste, strips, or trays (we're big fans of Crest 3D White Whitestrips Gentle Routine Teeth Whitening Kit, which is gentle enough for sensitive teeth). You can also prevent discoloration by getting regular dental cleanings and brushing your teeth after drinking red wine, coffee, and soda, or eating foods with sticky sauces such as barbecue or soy—some of the worst culprits. 

Like sipping through a straw, the repetitive motion of looking down at your smartphone can eventually cause rings to show up on your neck. “Fine lines and wrinkles can form over decades’ time through repeat motions,” says Dr. Nussbaum.

While there’s no fast fix, maintaining good posture and holding your smartphone at eye level can help. Dr. Nussbaum also recommends applying a firming lotion daily. “I favor lotions that are formulated with antioxidants and ingredients like shea butter and argan oil,” she says.
